Vent Termination Clearances - Comfort Bilt HP21 Owner's Manual

Installation

Vent Termination Clearances

The stove vent must terminate on the outside of the building. Horizontal terminations must extend a minimum
of 12" from the wall. Vertical terminations must protrude a minimum of 24" from the roof surface.
In addition, all clearances listed below must be met.
Must have an approved cap (to prevent water from entering) or a 45 degree downturn with rodent screen.
If the termination is located on a windy side of the house, we suggest using an approved house shield to
prevent soot from building up on the side of the house.
A vent must not be located where it may become plugged by snow or other material.
A: Minimum 48" clearance below or beside any door or window that opens. (This clearance may be reduced to
18" if using outside air). We recommend the door or window be kept closed during operation. Minimum 12"
clearance below or beside any window that does not open.
B: Minimum 12" clearance above any door or window that opens.
C: Minimum 24" clearance from any adjacent building.
D: Minimum 7' clearance above any grade, when adjacent to public walkways.
E: Minimum 24" clearance above any grass, plants, or other combustible materials.
F: Minimum 36" clearance from any forced air intake of another appliance.
G: Minimum 24" clearance below eaves or overhangs.
H: Minimum 12" clearance horizontally from combustible wall.
X: Must be a minimum of 24" above the roof.
NOTICE:
Do NOT terminate vent:
In any location that will allow flue gasses or soot to enter or stain the building.
In any location which could create a nuisance or hazard.
In any enclosed or semi enclosed area such as a carport, garage, attic, crawl space, under a sun deck
or porch, or narrow walkway.
Closely fenced area, or any location that can build up a concentration of fumes such as a stairwell,
covered breezeway, etc...
Do NOT terminate vent below air inlet.
It is recommended that at least 3 ft of vertical pipe be installed when the stove is vented directly
through a wall - this will create a natural draft, which will help prevent the possibility of smoke or odor
venting into the home during a power outage.
